From ScienceDaily:
Japanese researchers from Osaka University have uncovered a way in which our cells regulate the repair of broken DNA. Their results, published in the journal “Cell Reports,” show a common molecule regulates multiple repair mechanisms and help shed light on how the cell maintains the integrity of the human genome when it is damaged.
The human body consists of trillions of cells, and within each are billions of DNA molecules. Strict maintenance of the molecules is essential to maintain a healthy cell and thus a healthy body.
This maintenance is challenged by the daily bombardment of chemicals, UV light, radical oxgen and radiation that can damage the DNA molecules. If left unrepaired, the damage could lead to genomic instability and cell death. Thankfully, evolution has created in the cell innate repair mechanisms to fix any damaged DNA. Paper.

Note: “Thankfully, evolution has created in the cell innate repair mechanisms to fix any damaged DNA.” If “Evolution” “has created” these innate repair mechanisms, it must be functioning as some kind of an intelligent force.
Note also the assumption just shoved under the rug here: Life forms seek to repair themselves.
Inanimate objects do not seek to repair themselves. What is the nature of the difference between life and non-life that life seeks to continue in its live, healthy state? More, the mere fact that a life form would like to repair itself does not mean that it will have a repair kit handy. That is a separate issue that can’t be papered over by throwaway remarks such as “evolution has created…” Words should mean something.
These researchers should just go ahead and do their work, but we need to see that Darwinian assumptions are breaking down under the weight of the language nlanguage needede these situations.
